Hi, folks,

I might be wrong looking for help in this forum but as it is related to
the topic I hope someone can give me a usefull advice or an idea where
I can find related information to solve the following problem:
=====
I am trying to compile a new kernel on my machine (MA) for anathor
machine (MB) that I am using as firewall, where I need extended iptables
support.

MB is very slow and does not have enough diskspace, so I can not install
compilers or headers there.
Tehre is enough space for a new kernel though.

What I was trying ot do is to compile the kernel on MA and to install it
after I nfs-mount the linux-directory from MA to MB.
Unfortunately a developers environment on MB is missing and I got
following error after i do
make install

make: *** No rule to make target
`/usr/src/kernel-source-2.4.20/include/asm/param.h', needed by
`/usr/src/kernel-source-2.4.20/include/linux/sched.h'.  Stop.

Unfortunately on MA everything is compiling fine - where is the problem
what do I need for the asm/param.h

Is it enough to compile on MA and to copy the relevant stuff eg. vmlinuz
+ modules to MB

thanks a lot

After you compile the kernel, merely copy over the following files :

- /usr/src/linux-2.4.20/arch/i386/boot/bzImage
- /usr/src/linux-2.4.20/System.map
- /lib/modules/2.4.20/*

to the relevant paths at MB. Most probably /boot/ and /lib/. If you've made
changes to the iptables stuff, copy over the binary + relevant shared
libraries (.so files); those might be in different places. Try the
following paths for starters :

/lib/iptables/
/usr/local/lib/iptables/

If you still can't find it, try doing 'strace /path/to/new/iptables/binary
-L -n', and look for the open() calls to see which library path its looking
at. Reboot && voila :)
